FIELD OF INVENTION

The present invention concerns a wrapped scented toilet paper roller.

BACKGROUND OF THE INVENTION

There are many products on the market aimed at improving the scent of the air in household rooms. One such product is a scented toilet paper roller. A known roller has a cavity containing scented beads and a number of openings to allow the scent from the beads to be released into the air. The roller supports a roll of toilet paper in a conventional toilet paper holder.

An example of a known scented roller is described in U.S. Pat. No. 4,759,510, Singer. The patent is directed towards a universal scent-emitting toilet paper roller. The roller is described as including three components molded of thermoplastic material. Two of these components are identical vented hollow closed ended generally cylindrical roller halves, each half containing tongues and slots which permit the two roller halves to be axially slidably joined together. The third thermoplastic component is a helical coiled spring designed to fit inside the joined together roller halves and urge the two halves into their maximum axially extended position. A recessed truncated conical projection axially centered on the closed end of each roller half fits the assembled roller into a rolled paper dispenser. A quantity of scent-emitting pellets are contained within the hollow interior of the joined together roller halves to be tumbled about as the roller is rotated by the removal of paper, thus causing scent to be emitted into the atmosphere through vents in the roller.

SUMMARY OF THE INVENTION

One embodiment of the present invention is an individually-wrapped, scented toilet-paper roller. The roller is enclosed in a metalized film wrapper. The wrapper may be metalized polyester (PET), as this is preferred.

DETAILED DESCRIPTION OF THE EMBODIMENT

One example of the invention is further described in detail as follows. The wrapped scented toilet paper roller 10 includes a scented toilet paper roller 20 sealed and encompassed in a metalized wrapper 30. The scented toilet paper roller 20 comprises a roller 40 a, 40 b, a compression spring 50 disposed within the roller, scented beads 60, and scented oil 70 disposed on the scented beads.

The roller 40 a, 40 b includes a first roller half 40 a and a second roller half 40 b. The first and second roller halves 40 a, 40 b each have a curvilinear wall 41 a, 41 b disposed around the rollers longitudinal axis 90. Each curvilinear wall 41 a, 41 b extends along the length of the longitudinal axis 90. Each curvilinear wall has an inner surface 42 a, 42 b. Each inner surface defines at least in part, hollow roller chambers 43 a, 43 b.

Each roller half 40 a, 40 b has an end wall 44 a, 44 b. Each end wall 44 a, 44 b is disposed towards an end of each roller half 40 a, 40 b. Each roller half, opposite each end wall 44 a, 44 b, has an open end 45 a, 45 b, Each open end opens into each roller halves respective roller chamber 43 a, 43 b.

The first roller half 40 a has an outer diameter 400 a greater than the outer diameter 400 b of the second roller half 40 b. The second roller half open end 45 b is disposed within the first roller half open end 45 a so that the first roller chamber 43 a and second roller chamber 43 b form a continuous roller chamber 43 a, 43 b extending along the length of the rollers longitudinal axis 90.

The second roller half 40 b is telescopically engaged within the first roller half 40 a. Thus the first and second roller halves are slidably movable, relative to each other, along the rollers longitudinal axis 90 to allow the roller 40 a, 40 b to be adjusted from a retracted position. See FIG. 11 to an expanded toilet tissue installation position. See FIG. 4.

The compression or coil spring 50 is disposed within the roller chamber 43 a, 43 b. The compression or coil spring has a first end coil 51 a abutting up against first roller half end wall 44 a. The compression spring 50 has a second end coil 51 b axially opposite the first end coil 51 a. The second end coil 51 b abuts up against an end wall 46 b bounding the open end 45 b of the second roller half 40 b. An end wall 46 a also bounds open end 45 a of the first roller half 40 a. The end wall 46 a forms an outermost shoulder of the scented roller 20.

In the expanded installation position, the compression spring 50 biases the roller halves with a force so each roller half is pushed in a direction axially opposite the other roller half. The roller 40 a, 40 b has a retention mechanism to ensure that the first roller half 40 a and second roller half 40 b, in the expanded installation position, remain telescopically engaged in an orientation which applies a compression force to the spring. A force applied to both or either roller half 40 a, 40 b, in a direction toward a roller half open end 45 a, 45 b and along the roller's longitudinal axis 90 will cause the roller halves to further compress spring 50 and to each move toward the other into a contracted position. In the present embodiment, the compression spring is disposed within the first roller chamber 43 a. Other dispositions of the roller spring are possible.

In more detail, the retention mechanism includes a protrusion 81. The protrusion 81 extends inward towards the longitudinal axis 90 from the first roller half inner surface 42 a. The protrusion 81 extends in a direction transverse to longitudinal axis 90. Although the protrusion is shown as an unbroken cylindrical shoulder, it could have other configurations. The protrusion has an end surface 82 facing the first roller half open end 45 a. The end surface 82 is oriented in the same direction relative to the longitudinal axis as is the first roller half open-end wall 46 a. The protrusion 81 has a ramped surface 83. The ramped surface 83 slopes inward from end surface 82 towards the first roller half inner surface 42 a.

The retention mechanism further includes a portion 411 of the second roller half wall 41 a. The portion 411 has an expanded diameter. The surface of wall portion 411 having the expanded diameter is brushed as opposed to slick. A ledge 412 is formed between wall portion 411 and an adjacent remaining portion of the second roller half wall 41 a. In the roller expanded position, the expanded wall portion 411 is axially further away from first roller half open end 45 a than is the protrusion 81. The spring remains slightly compressed, thereby exerting forces on each roller half 40 a, 40 b to force the ledge 412 to abut up against the protrusion 81.

Each end wall 44 a, 44 b of each roller half 40 a, 40 b has distinct portions. Each end wall has a conical protrusion 441 a, 441 b tapering along longitudinal access 90 in a direction opposite its respective roller halves open end. Each end wall also includes a second plateau 442 a, 442 b perpendicular to the longitudinal axis. Each conical portion 441 a, 441 b extends outwardly from its respective second plateau 442 a, 442 b, along longitudinal axis 90, and away from the open end of its respective roller half. Each end wall further includes a first plateau 443 a, 443 b concentric to and parallel to the second plateau. Each first plateau 443 a, 443 b is joined to its respective second plateau 442 a, 442 b and spaced axially therefrom by a cylindrical shoulder 444 a, 444 b. Each cylindrical shoulder 444 a, 444 b is perpendicular to the first and second plateau which it joins. Each first plateau 443 a, 443 b is comprised of a series of ribs or spokes disposed circumferentially around its respective cylindrical shoulder. The first plateau 443 a, 443 b can be referred to as a first platforms. The second plateaus 442 a, 442 b can be referred to as a second platforms. The second plateaus protrude from the their respective first plateaus in the axial direction and away from the open end of their respective roller halves.

The roller walls 41 a, 41 b each have solid cylindrical portions 415 a, 415 b and ribbed portions 416 a, 416 b. Protrusion 81 emanates from the inward surface 42 a of the first roller half solid wall portion 415 a. The extended wall 411 portion forms part of the second roller half solid wall 415 b. The ribbed sections 416 a, 416 b of each roller half includes a plurality of ribs 4116 a, 4116 b which are substantially parallel to each other. The ribs are also substantially parallel to the longitudinal axis 90. The ribs are disposed about the longitudinal axis 90. Sixteen of the ribs 4116 a form the ribbed portion of the first roller half. Sixteen of the ribs 4116 b also form the ribbed portion of the second roller half. The ribs 4116 a on the first roller half are spaced such that a chasm 417 a of about {fraction (1/16)} of an inch exists between each pair of adjacent ribs. A space between each of the ribs on the second roller half forms a chasm 417 b between each rib which is also {fraction (1/16)} of an inch. The ribs 4116 b of the second roller half have a thickness slightly less than the thickness of the ribs 4116 a of the first roller half. The second roller half has an outer diameter 400 b of about ¾ of an inch. The second roller half ribs have a width to ensure the {fraction (1/16)}th of an inch spacing between each rib. The first roller half has an outer diameter 400 a which is about {fraction (15/16)} of an inch. The ribs of the first roller half have a width to allow for the {fraction (1/16)} of an inch spacing between each rib.

Each ribbed section 416 a, 416 b of each roller half has an internal support 418 a, 418 b to help stabilize the relative position of each rib relative to the roller's longitudinal axis 90. The support 418 a for the ribbed section of the first roller half forms an internal hoop, is transverse to the roller's longitudinal axis, and parallel to the first roller half end wall 44 a. The hoop extends along the internal surface 42 a of the ribs 4116 a forming the first roller half ribbed portion 416 a. The support for the ribs 4116 b of the second roller half is similarly fashioned as the support for the first roller half.

The first roller and second roller half each have a total length 91 a, 91 b of 3⅜″. The ribs of the first roller half have a length 92 a of 1¾″. The ribs of the second roller half also have a length 92 b of 1¾″. The wall portion having the expanded diameter 411 has a length 933 of {fraction (9/16)} of an inch. The first and second roller halves solid wall portions each have a longitudinal length 93 a, 93 b of 1{fraction (3/16)}″.

The second plateau on each end wall is an axial distance 94 a, 94 b from its respective first platform of {fraction (3/16)} of an inch. The conical portion of each end wall has a length 95 a, 95 b which extends about {fraction (4/16)} of an inch axially outward from the second plateau. The second platform of the second roller half has a diameter 401 b of about ½″. The second platform of the first roller half has a diameter 401 a of about ⅝″. The base portion of each end wall's conical member has a diameter 402 a, 402 b of about ¼″.

The proportional relationship between the dimensions of each part of the roller are believed to have importance. Proportional relationships, though not specifically stated herein are easily calculated based on the dimensional disclosures herein.

The scented roller is sealed within metalized wrapper 30. The wrapper is disposed around the scented roller 20 so as to provide a substantially airtight barrier around the roller. The metalized wrapper is preferably aluminum 31 coated with polyester 32. The beads disposed within the roller are scented. The beads are made out of a resilient soft plastic. The beads 60 are scented. The scented beads have applied thereto a layer of scented oil 70.
